I agree with Don (as almost always :-) ). The other thing that comes
to mind is to ask if you have remembered to re-tighten the screws
securing the PA transistors to the heat sink. This sounds like it
could be a failure due to overheating PA transistors. Over that
period of time, with a loose heat sink, this situation could come up...
Now its time for the contest...

Rich,
Anytime you see the Elecraft message in the display it means that
somehow
the voltage supplied to the K2 has dropped significantly.
Check your power supply wiring. Use 16 guage wire or larger and be
certain
all the connections are tight and the connector that plugs into the
K2 is
properly soldered to the wires.
There are a few components in the K2 that could be at fault - the
series
diode or resettable fuse in the +12 volt line are the prime
suspects, but
they seldom fail themselves - virtually all problems of that sort
can be
traced to a bad solder connection in the power wiring.

I have a weird problem. I'm running my K2 about 10 watts into an
amplifier.
When I am in a ragchew QSO on CW, the K2 stops keying after about
60-90
seconds. In other words it doesn't go into TX at all. I get an
elecraft
message on the display and my Split operation disappears After I
wait for
about 15 seconds turn split again , the K2 works fine until the
next 90
seconds. Where do I look ? Same thing happens if I run the K2
barefoot,
10 watts without the amp.
Thanks for any reply
